No, they only effect Lobsters, Tuna, Swordfish and Sharks if I remember right. The chief guy you get then from tells you what they effect. (Which is four fish, I'm unsure of Tuna/Swordfish but I'm sure lobster and sharks work)

And stopping at 94 is sharks, not monkfish. There is no level you stop burning monkfish, though some think gauntlets burn less.

An intensive study has shown that cooking gauntlets affect monkfish cooking success, but only slightly. At cooking levels over 80, the improvement rate averaged a mere 2.5%. Stop burning levels are not available at this time. Jagex has not announced any affect of gauntlets on cooking monkfish.
